Mounting grooves 246 may be formed at the pads 241 to 245 where theelectrode modules 251 to 255 are inserted.

A through-hole 247 may be formed through the bottom of the mountinggroove 246. The through-holes 247 may extend or diverge from the cable300 to connect the transmitting lines 310 (see FIG. 8) for transmittingRF energy to the electrode modules 251 to 255 in the correspondingmounting grooves 246 and/or the signal line 320 (see FIG. 8) fortransmitting various control signals to the electrode modules 251 to255.

Alternatively, circuit boards (not shown) transmitting the RF energytransmitted through the cable 300 to the electrode modules 251 to 255 inthe corresponding mounting grooves 246 may be further disposed on thebottoms of the mounting grooves 246.

In this configuration, the circuit board can be connected with thetransmitting lines 310 and/or the signal line through the through-holes247 and the electrode modules 251 to 255 can receive RF energy throughthe circuit boards.

On the other hand, the pads 241 to 245 may be connected with adjacentpads 241 to 245 by flexible elastic portions 248. The flexible elasticportions 248 may be made of a synthetic resin-based material havingelasticity rapidly returning to the initial shape when an external forceis removed, even if they are deformed such as bending by the externalforce.

When the electrode mount 240 with the electrode modules 251 to 255 isdeformed and some of the pads 241 to 245 are pressed on a part with manyconvex curves of a human body, the pads around connected by the flexibleelastic portions 248 surround the part of the human body, such that theelectrode modules 251 to 255 can be efficiently brought in contact withthe part of the human body.

A plurality of elastic member support pins 222 correspond to the regions223 to 227 of the pads may be formed on one side of the elastic membersupport 220. For example, as shown in FIG. 6, the elastic member supportpins 222 may be arranged in a rectangular shape in the region 223corresponding to the center pad 241 and may be arranged to correspond tothe corners of the pads 242 and 243 in the regions 224, 225, 226, and227 corresponding to the upper pad 244, the lower pad 245, the left pad242, and the right pad 243, respectively.

Since the elastic member support pins 222 are arranged, as shown in FIG.6, the elastic members 230 can firmly elastically support the pads 241to 245, even if the pads 241 to 245 are moved in different directions bycurves on a human body.

On the other hand, as shown in FIG. 2, the elastic member support 220may be inserted and fixed inside the handpiece 200. In thisconfiguration, a protruding support step 212 may be formed on the innerside of the handpiece 200 and at least one of support bars 213 radiallyextending from the support step 212 may be formed to more firmly supportthe elastic member support 220. Second connecting holes 214corresponding to the connecting holes 221 may be formed at the supportbars 212 and/or the support step 213.

The elastic member support 220 is formed in the handpiece 200 and theelastic members 230 are mounted on the elastic member support pins 222of the elastic member support 220, respectively. The elastic members 230may be coil springs having a restoring force against force thatcompresses the elastic members 230.

Elastic member grooves where ends of the elasticmembers 230 are fitted or support pins similar to the elastic membersupport pins 222 of the elastic member support 220 may be formed on theother sides of the pads 241 to 245 in order to firmly and elasticallysupport the pads 241 to 245 to the elastic members 230 even if they aremoved by curves of a human body.

The electric modules 251 to 255 are disposed on the pads 241 to 245,respectively. When the mounting grooves 246 are formed on the pads 241to 245, the electrode modules 251 to 255 are inserted in the mountinggrooves 246. One side of each of the electrode modules 251 to 255 mayprotrude further than one end of the handpiece 200.
